This research focuses on a new softening technology for use with chicken breast and eye of round beef in order to assist elderly individuals who have difficulty with eating due to changes in their ability to chew (masticatory function) or swallow. We investigated the hardness of chicken breast and eye of round beef through use of a texture analyzer after injection of a commercial enzyme. Among 7 commercial enzymes, bromelain and collupulin exhibited a marked softening effect on the tested chicken breast and eye of round beef given a 1.00% enzyme concentration. The hardness of bromelain-treated chicken breast reached 1.4×10⁴ N/m², of collupulin-treated chicken breast reached 3.0×10⁴ N/m², and of bromelain-treated eye of round beef reached 3.2×10⁴ N/m², respectively, while their original shapes did not change. To find the level of tissue degradation with specific enzyme concentrations, enzyme injections at 0.1%, 0.25%, 0.50%, and 1.00% concentration of bromelain and papain were also evaluated. The results of this research could be useful for softening chicken breast and eye of round beef and will contribute to the development of foods that can be more easily eaten as part of a balanced diet for elderly adults.

The efficacy of the radioprotective effect of Callophyllis japonica ethyl acetate (CJEA) extract was studied by comparing it to that of amifostine, a well-known radioprotective agent, and by evaluating the dose reduction factor, an indicator of radioprotective efficacy. Pretreatment with CJEA extract (100 mg/kg body weight) prior to receiving 12 Gy irradiation significantly improved the survival of jejunal crypts at 3.5 day post-irradiation, but attenuated the level of malondialdehyde compared to vehicle alone (P < 0.01). A similar gastroprotective effect was also obtained in the amifostine-treated irradiated group (P < 0.01). The efficacy of the radioprotective effect was further confirmed by the dose reduction factor, 1.41. Collectively, these results suggest that CJEA extract is a useful radioprotectant whose efficacy is similar to that of amifostine and whose radioprotective mechanism is in part the reduction of lipid peroxidation caused by gamma irradiation.

To obtain the useful information for the status of working environment and health management of workers in manufacturing industries, comparision of results on the status of working environmental and health management of workers for 32 manufacturing industries in Chunan area from 1988 to 1989 was carried out. The results were as follows : 1. The rate of over-PEL (Permissible Exposure Limit) to for hazardous factors decreased significantly 23.5% in 1988, 18.3% in 1989 (p<0.05) and, the highest rate of over-PEL was the stone and sand handling industry, the highest rate of over-PEL was the dusty workplace as 38.5% in 1988, 35.2% in 1989. 2. The rate of workers exposed to hazardous factors in 1988 and in 1989 was 22.4% respectively, the rate of workers checked up special health examination was 40.1% in 1988, 75.3% in 1989. In stone and sand handling and medicochemical industries, none of workers exposed to hazardous factors was subjected to special health examination in 1988, but 75% of workers exposed to hazardous factors had checked up in 1989. 3. The 6 industries appointed as part-time factory physician among 17 industries which were supposed to have factory physician according to the Safety and Healthy Act of Korea, 6 out of 24 industries only appointed industrial hygienist, furthermore 4 out of 6 hygienists had another duty in addition to occupational hygiene itself.

This paper is an attempt to find/make an entrance to John Hejduk's architecture. Based explicitly on both Karl Popper's model of knowledge production called 'conjecture and refutation' and Harold Bloom's theory of poetry called 'revisionism', this paper, in order to produce a new problem, mainly deals with an existing knowledge as an object to refute, that is, Michael Hays' interpretation of Wall House by Jacques Lacan's notion of the gaze, Hejduk's a pivotal architectural finding. The arguments underlying this paper are two: First, Hejduk, just like this paper, follows Popper's model and Bloom's theory in conducting his own architectural research. Secondly, he takes what might be called artist's attitude when absorbing previous knowledge and producing new one. These two arguments are made in the first part and then served as a basic propositions for further arguments. In the process of criticizing the way in which Hays explicates Hejduk's Wall House, this paper reaches two main arguments. First, Lacan's notion of the gaze is not proper specifically for the explication of it. However, it may be useful and even promising when dealing with other works such as Subject/Object and House of the Inhabitant Who Refused to Participate. Secondly, Freud's notion of 'uncanny', arguably Hejduk's strong architectural orientation, may serve much better as a main gate among possibly many ones in trying to open his architecture. It is considered that this might also serve as an important clue to solving mysticism remaining yet untouched in his architecture.

A model for the role of serum was proposed to develop a low serum medium for the large scale cu1ture of mammalian cell. The strategy of medium development adopted in this study facilitated the understanding of the role being carried out by the serum in the culture of hybridoma KAl12 cell line. In this model, the serum components were divided into two main groups : the first group encompasses the nutrient factors that determine the maximum cell density and the second group includes the growth factors that regulate the cell growth rate, The model prediction was compared with the experimental results. The model enabled us to find out several useful aspects of medium composition for cell growth. 1) One particular component in the basal medium became limiting factor when serum concentration level was more than 7%. 2) The growth regulating factors and nutrient factors limited the cell growth at 3% and 5% serum concentration levels respectively.

The aim of the present paper is to develop a computer program predicting ultimate fracture strength of initially cracked structure under monotonically increasing external loads. For this purpose, two kinds of 3-D isoparametric solid elements, one 6-node wedge element and another 8-node brick element are formulated along the small deformation theory. Plasticity in the element is checked using von Mises' yield criterion. Elasto-plastic stiffness matrix of the element is calculated taking account of strain hardening effect. If the principal strain at crack tip which is one nodal point exceeds the critical strain dependin on the material property, crack tip is supposed to be opened and the crack tip node which was previously constrained in the direction perpendicular to the crack line is released. After that, the crack lay be propagated to the adjacent node. Once a crack tip node is fractured, the energy of the newly fractured node should be released which is to be absorbed by the remaining part. The accumulated reaction force which was carried by the newly fractured node so far is then applied in the opposite direction. During the action of crack tip relief force, since unloading may be occured in the plastic element, unloading check should be made. If a plastic element unloads, elastic stress-strain equation is used in the calculation of the stiffness matrix of the element, while for a loading element, elasto-plastic stress-strain equation is continuously used. Verification of the computer program is made comparing with the experimental results for center cracked panel subjected to uniform tensile load. Also some factors affecting ultimate fracture strength of initially cracked plate are investigated. It is concluded that the computer program developed here gives an accurate solution and becomes useful tool for predicting ultimate fracture load of initially cracked structural system under monotonically increasing external loads.

There has been a lot of researches on the major motivation of consumer's choice for airlines. Due to the competition in airline industries, most of airlines offer a various level of benefits to customers such as a frequent traveller bonus, a schedule, services in flight including a meal and an entertainment program, a discounted fare and an intangible part of personal service. However, it is very difficult to measure the performance of the customers' benefit and to identify the weight of each factor being considered on the airline choice. In this paper, we focus on the airline choice process for the business travellers. The AHP is applied to evaluate the factors reflecting the business travellers' choice for airlines. This study will be useful to build a marketing plan for the business traveller's market.
